Cost-effectiveness analysis of population-based screening of hepatocellular carcinoma: Comparing ultrasonography with two-stage screening

Figure 2 Cost-effectiveness of hepatocellular carcinoma screening with selected initial ages and selected screening intervals. The reference strategies were non-screening programs at the index initial ages. A: Strategies are labeled by the type and initial ages of screening; B: Strategies are labeled by the type and frequency of screening. AUS: Abdominal ultrasonography mass screening; Two: Two-stage biomarker-ultrasound screening.
